The historical epic drama is based on the life of the warrior Zhao Yun in the classic novel “Romance of the Three Kingdoms.” YoonA is one of the leads of the show, and her character is the love interest of both Zhao Yun, played by Lin Gengxin, and Li Zhi, played by Kim Jung Hoon.

On April 30, her co-star Sun Xiao Xiao uploaded two shots of herself and YoonA behind the scenes at a press conference for the show to her Weibo. They’re both cozying up together looking like the best of friends in the costumes they wear in the drama, complete with beautiful hair accessories.
